Identify Oversized Domino Tiles?

Q: Hello AT! Is there anyone out there who can identify these domino tiles, seen in the latest West Elm catalog? A search for "domino" on the West Elm website yields no results, and a Google search yields results for pizza and style magazines.

Please help — the game holds a special significance for me, and I'd love to display a decorative, oversized tile somewhere in my home.
